BACKGROUND

1. Field

The present invention relates to an electronic apparatus having a casingfor housing a speaker device.

2. Description of the Related Art

As an example of an electronic apparatus, there exists a portablecomputer in which a speaker device that reproduces sound, such as videoor music, is housed in a casing.

A speaker device of this type has a speaker main body and a speakerhousing for housing the speaker main body.

In a speaker device of this type, it is thought that the speaker housingis increased in size in order to improve sound quality.

On the other hand, for easy carrying of a portable computer, it isdesirable that the portable computer be formed in compact form.

Therefore, if the speaker housing is increased in size in a heightdirection for sound quality improvement, the thickness of the portablecomputer increases, resulting in an increase in the size of the portablecomputer.

If the speaker housing is increased in size in a width direction, thearea occupied by the speaker housing within the casing of the portablecomputer increases. In this case, in order to prevent interferencebetween other components, such as a PCB (printed circuit board), housedin the casing of the portable computer and the speaker housing, theother components such as the PCB need to be reduced in size. It is notdesirable to reduce the size of the other components such as the PCB.

In view of this, a speaker device is proposed which achieves soundquality improvement by changing the capacity of a speaker housing when aportable computer is in use. For example, Jpn. Pat. Appln. KOKAIPublication No. 2004-56185 discloses such a speaker device.

In the speaker device disclosed in Jpn. Pat. Appln. KOKAI PublicationNo. 2004-56185, however, part of the speaker housing projects over aplane where a keyboard is provided, because the capacity of the speakerhousing is changed. Accordingly, the user may find the usability of theportable computer to be poor.

FIG. 2 is a cross-sectional view of the portable computer 10 taken alonga line extending through the speaker device 50 from the front to therear of the portable computer 10. FIG. 3 is a perspective view of a partof the bottom wall 24 a of the portable computer 10 where the speakerdevice 50 provided at the rear-right side portion 53 is present, asviewed from the outside.

As shown in FIG. 2, the speaker device 50 has a speaker housing 54 and aspeaker main body 55. The speaker main body 55 is housed in the speakerhousing 54.

As shown in FIGS. 2 and 3, a swelling portion 71 is formed at a location70 of the bottom wall 24 awhere the speaker device 50 is to be disposed.The swelling portion 71 is formed by part of the bottom wall 24aswelling outward. Thus, the swelling portion 71 has a depression shapewhich opens upward.

Note that although in the present embodiment the locations 70 where thespeaker devices 50 are to be disposed are present at part of the firstcasing 21, i.e., the rear-left side portion 52 and the rear-right endportion 53, the present invention is not limited thereto. The locationswhere the speaker devices 50 are to be disposed can be arbitrarily set.

As shown in FIG. 3, the swelling portion 71 has a swelling portion mainbody 72 and a projection portion 73 that projects from the swellingportion main body 72 toward, for example, the right side.

As shown in FIG. 2, the swelling portion main body 72 has a size whichallows part of a bottom portion 54 a of the speaker housing 54 to behoused in the swelling portion main body 72. A bottom of the speakerhousing 54 refers to an underside 54 bof the speaker housing 54 which isthe opposite side of where sound is emitted.

A cushioning material 80 is provided between an inner surface of theswelling portion main body 72 and the speaker housing 54. The cushioningmaterial 80 absorbs vibration of the speaker device 50.

The speaker housing 54 is disposed in the first casing 21 such that partof the bottom portion 54 aof the speaker housing 54 is housed in aninner space 74 of the swelling portion main body 72. FIG. 4 is a planview, in which the top wall 23 aand the keyboard retaining member 25 arepartially cut away, showing a state in which part of the bottom portion54 aof the speaker device 50 is housed in the inner space 74 of theswelling portion main body 72. Note that although FIG. 4 shows thevicinity of the speaker device 50 disposed at the rear-left side portion52, the vicinity of the speaker device 50 disposed at the rear-rightside portion 53 may be substantially the same.

As shown in FIGS. 2 and 4, the PCB 60 is large in size such that the PCB60 reaches the vicinity of the speaker device 50.

As shown in FIG. 4, in the vicinity of the swelling portion 71 of thefirst casing 21, there are provided boss portions 75 through whichbolts, for example, that engage the cover portion 23 and the baseportion 24 pass, a vertical wall portion 76 used to house othercomponents, such as the PCB 60, in the first casing 21, and the like.The boss portions 75 and the vertical wall portion 76 can be provided toeither the base portion 24 or the cover portion 23.

A cushioning material 80 is provided between the boss portion 75 and thespeaker housing 54 and between the vertical wall portion 76 and thespeaker housing 54. As shown in FIG. 2, the hinge 40 is located abovethe speaker housing 54. The hinge 40 has provided therein a through hole41 so as to accommodate the speaker housing 54.

Now, the through holes 51 and 26 provided in the top wall 23 aand thekeyboard retaining member 25 will be described. The through hole 51provided in the top wall 23 ais smaller than a top side 54 cof thespeaker housing 54. Thus, a rim portion 51 aof the through hole 51provided in the top wall 23 a overlaps part of the top side 54 c of thespeaker housing 54 in the up-down direction.

FIG. 5 is a plan view showing the inside of the cover portion 23. Asshown in FIGS. 2 and 5, cushioning materials 80 are provided at the rimportion 51 aof the through hole 51 provided in the top wall 23 a. Thetop wall 23 aretains the position of the speaker housing 54 by holdingdown, through the cushioning materials 80, the speaker housing 54 fromthe above.

As shown in FIG. 2, a covering member 61 for covering the through hole51 is provided at the rim portion 51 aof the through hole 51 provided inthe top wall 23 a. The covering member 61 has a frame portion 62 and amesh portion 63. The frame portion 62 overlies the rim portion 51 aofthe through hole 51 from above. The frame portion 62 has a hole 64 on aninner side thereof. The hole 64 faces the top side 54 cof the speakerhousing 54. The mesh portion 63 covers the hole 64 provided on the innerside of the frame portion 62. The mesh portion 63 is mesh-like.

The covering member 61 thus formed is overlaid, from above, on the rimportion 51 aof the through hole 51 provided in the top wall 23 a. Bythis, the through hole 51 is covered by the covering member 61.

The through hole 26 provided in the keyboard retaining member 25 has asize which allows a rim portion 26 aof the through hole 26 to overliepart of an exterior of the frame portion 62 of the covering member 61 inthe up-down direction. Accordingly, when the keyboard retaining member25 is overlaid on the top wall 23 a, the keyboard retaining member 25holds down the frame portion 62 of the covering member 61. By this, thecovering member 61 is retained between the top wall 23 aand the keyboardretaining member 25.

The top wall 23 ahas a two-step-down shape so as to accommodate thekeyboard retaining member 25 and the covering member 61. The coveringmember 61 is provided on a first step surface 81 of the top wall 23 a.The keyboard retaining member 25 is provided on a second step surface 82of the top wall 23 a. The depth of the second step of the top wall 23ais substantially the same as the thickness of the keyboard retainingmember 25. Thus, a top side of the top wall 23 ais substantially flushwith a top side of the keyboard retaining member 25.

As shown in FIG. 3, an underside 73 aof the projection portion 73 and anunderside 72 aof the swelling portion main body 72 are, for example,substantially in the same plane. A rubber foot 83 is provided on theunderside 73 aof the projection portion 73. The rubber foot 83 alsocovers a part 200 of the underside 72 aof the swelling portion main body72.

In FIG. 2, the rubber foot 83 is shown by a dash-double-dotted line. Asshown in FIG. 2, in the present embodiment, the portable computer 10 isplaced on a top side 91 of a table 90, and a tip 83 aof the rubber foot83 facing the top side 91 projects most significantly toward the topside 91 of the table 90.

Therefore, when the portable computer 10 is placed on the top side 91 ofthe table 90, the rubber foot 83 abuts on the top side 91. That is, theswelling portion 71 functions as a foot portion of the portable computer10. The rubber foot 83 has an anti-slip function. The table 90 is, asreferred to in the present invention, an example of the mountingportion.

Note that the rubber foot 83 should project most significantly towardthe top side 91 of the table 90. Hence, the underside 73 aof theprojection portion 73, for example, does not need to project mostsignificantly toward the top side 91.

In this case, with the height of the rubber foot 83 being added to theunderside 73 a, the tip 83 aof the rubber foot 83 projects mostsignificantly toward the top side 91.

The retaining structure of the speaker device 50 provided at therear-left side portion 52 is also substantially the same as theretaining structure of the speaker device 50 provided at the rear-rightside portion 53.

In the portable computer 10 thus configured, part of the speaker housing54 is housed in the inner space 74 of the swelling portion main body 72.Therefore, the height of the speaker housing 54 can be increased by anamount equal to the depth of the inner space 74 of the swelling portionmain body 72. That is, the capacity of the speaker housing 54 can beincreased. Accordingly, sound quality is improved.

Furthermore, portions of the first casing 21, other than the swellingportion 71, are not increased in size. Hence, without increasing theoverall size of the first casing 21, the first casing 21 can house thespeaker housing 54 with a large capacity.

The swelling portion 71 swells outward from the bottom wall 24 a. Thus,even when the first casing 21 houses the speaker housing 54 with a largecapacity, the top wall 23 adoes not swell upward. Hence, the usabilityof the portable computer 10 is not impaired.

Accordingly, the portable computer 10 achieves sound quality improvementand good usability while suppressing an increase in the size of thefirst casing 21.

Since the swelling portion 71 is formed using part of the bottom wall 24a, the swelling portion 71 can be easily formed.

The swelling portion 71 functions as a foot portion of the portablecomputer 10. Since a foot portion does not need to be additionallyprovided to the bottom wall 24 a, the configuration of the portablecomputer 10 is simplified.

The cushioning material 80 is provided between the speaker housing 54and an inner surface 72 bof the swelling portion main body 72. Thecushioning material 80 is provided between the speaker housing 54 andthe vertical wall portion 76. The cushioning material 80 is providedbetween the speaker housing 54 and the boss portions 75.

These cushioning materials 80 absorb vibration of the speaker housing54. By providing the cushioning materials 80 between the first casing 21and the speaker housing 54 in this manner, the vibration of the speakerhousing 54 is inhibited from being transmitted to the first casing 21.

Now, with reference to FIG. 6, an electronic apparatus according to asecond embodiment of the present invention will be described using aportable computer 10 as an example. Note that the configurations havingthe same functions as those in the first embodiment are denoted by thesame reference numerals and the description thereof is not repeated.

In the present embodiment, the height of a speaker housing 54 isdifferent from that in the first embodiment. Other structures may be thesame as those in the first embodiment. The difference will be describedin detail.

FIG. 6 is a cross-sectional view of the portable computer 10 of thesecond embodiment taken along a line extending through a speaker device50 from the front to the rear of the portable computer 10. As shown inFIG. 6, in the present embodiment, the height of the speaker housing 54is not increased according to the depth of an inner space 74 of aswelling portion main body 72. When the height of the speaker housing 54is not increased according to the depth of the inner space 74 of theswelling portion main body 72, i.e., when the capacity of the speakerhousing 54 is not increased, the length of the speaker housing 54 abovean inner surface of a bottom wall 24 a is shortened. Accordingly, theheight of a first casing 21 can be reduced.

Therefore, when the height of the speaker housing 54 is not increased,the height of the first casing 21 can be reduced. That is, the portablecomputer 10 can be reduced in size.

Now, with reference to FIG. 7, an electronic apparatus according to athird embodiment of the present invention will be described using aportable computer 10 as an example. Note that the configurations havingthe same functions as those in the first embodiment are denoted by thesame reference numerals and the description thereof is not repeated.

FIG. 7 is a cross-sectional view of the portable computer 10 of thethird embodiment taken along a line extending through a speaker device50 from the front to the rear of the portable computer 10. As shown inFIG. 7, in the present embodiment, the height of the speaker housing 54is not increased according to the depth of an inner space 74 of aswelling portion main body 72. When the height of the speaker housing 54is not increased, a clearance S is provided between the speaker housing54 and a top wall 23 a. Thus, the size of a PCB 60 can be increased tothe point that part of the PCB 60 enters into the clearance S.

In such a case, boss portions 92 extending to a top side 54 cof thespeaker housing 54 are formed on the top wall 23 a. Then, a cushioningmaterial 80 is provided between each of the boss portions 92 and thespeaker housing 54.

In addition, a cushioning material 80 is provided between the PCB 60 andthe speaker housing 54. Note that the component to enter the clearance Sis not limited to the PCB 60.

Now, with reference to FIGS. 8 and 9, an electronic apparatus accordingto a fourth embodiment of the present invention will be described usinga portable computer 10 as an example. Note that the configurationshaving the same functions as those in the first embodiment are denotedby the same reference numerals and the description thereof is notrepeated.

In the present embodiment, the location where a rubber foot 83 isprovided is different from that in the first embodiment. Otherstructures may be the same as those in the first embodiment. Thedifference will be described in detail.

FIG. 8 is a perspective view of the portable computer 10 of, showing apart of the bottom wall 24 aof the portable computer 10, where a speakerdevice 50 is provided at a rear-right portion 53.

FIG. 9 is a cross-sectional view of the portable computer 10 of thefourth embodiment taken along a line extending through the speakerdevice 50 from the front to the rear of the portable computer 10. Asshown in FIGS. 8 and 9, in the present embodiment, the rubber foot 83 isprovided over substantially the entire area of an outer peripheralsurface 78 of a swelling portion 71. In the present embodiment, it isnot necessary to form a projection portion 73.

In the present embodiment, the same advantageous effects as thoseobtained in the first embodiment can be obtained. Furthermore, with therubber foot 83 being provided over substantially the entire area of theouter peripheral surface 78 of the swelling portion 71, the rubber foot83 also effectively absorbs vibration of the speaker device 50.

Now, with reference to FIG. 10, an electronic apparatus according to afifth embodiment of the present invention will be described using aportable computer 10 as an example. Note that the configurations havingthe same functions as those in the first embodiment are denoted by thesame reference numerals and the description thereof is not repeated.

In the present embodiment, the structure of a swelling portion 71 isdifferent from that in the first embodiment. Other structures may be thesame as those in the first embodiment. The difference will be describedin detail.

FIG. 10 is a cross-sectional view of the portable computer 10 of thefifth embodiment taken along a line of extending through a speakerdevice 50 from the front to the rear of the portable computer 10. Asshown in FIG. 10, a through hole 93 is provided at a location 70 of abottom wall 24 awhere the speaker device 50 is to be formed.

A swelling member 94 is provided at a rim portion 93 aof the throughhole 93. The swelling member 94 has a depression shape which opensupward. The swelling member 94 is made of a rubber and has a size whichcovers the through hole 93. The swelling member 94 swells outward fromthe bottom wall 24 a.
